Silk fiber mechanics from multiscale force distribution analysis.
Here we decipher the molecular determinants for the extreme toughness of spider silk fibers. Our bottom-up computational approach incorporates molecular dynamics and finite element simulations. Therefore, the approach allows the analysis of the internal strain distribution and load-carrying motifs in silk fibers on scales of both molecular and continuum mechanics. We thereby dissect the contrib...
متن کاملInterspecific comparison of the mechanical properties of mussel byssus.
Byssally tethered mussels are found in a variety of habitats, including rocky intertidal, salt marsh, subtidal, and hydrothermal vents. One key to the survival of mussels in these communities is a secure attachment, achieved by the production of byssal threads. Although many studies have detailed the unique biomechanical properties of byssal threads, only a few prevalent species have been exami...
متن کاملMechanical design of mussel byssus: material yield enhances attachment strength
The competitive dominance of mussels in the wave-swept rocky intertidal zone is in part due to their ability to maintain a secure attachment. Mussels are tethered to the substratum by a byssus composed of numerous extracellular, collagenous threads secreted by the foot. Each byssal thread has three serially arranged parts: a corrugated proximal region, a smooth distal region and an adhesive pla...
متن کاملIn search of molecular dovetails in mussel byssus: from the threads to the stem.
We recently described the cDNA sequence for a unique collagenous protein, preCol-P, in the byssal threads of the marine mussel Mytilus edulis. The translated amino acid sequence encodes an unprecedented block-copolymer-like sequence with a central collagenous domain flanked by elastin-like sequences. Here, we report on the presence of two additional variants of preCol-P. The distribution of the...
متن کاملByssus attachment strength of two mytilids in mono-specific and mixed-species mussel beds.
The mussel Xenostrobus securis is endemic to the brackish waters of New Zealand and Australia, but has successfully invaded the inner Galician Rías of NW Spain, where it coexists with the indigenous mussel Mytilus galloprovincialis. In this laboratory study, the plasticity of the byssus attachment strength of two mytilids was compared by manipulating substratum, salinity, and bed assembly. M. g...
